You can activate and deactivate the bandwidth extension manually in the I/Q ana-
lyzer that is integral part of the optional spectrum analyzer (R&S FSWP-B1) or
other optional applications that require the spectrum analyzer hardware.
Together with the bandwidth extension an additional IF output connector is provi-
ded (if wide output). As opposed to the default IF / Video / Demod Output connec-
tor, the IF output frequency of the optional connector cannot be defined manually,
but is determined automatically depending on the center frequency. For details on
the used frequencies, see the data sheet. The IF Wide Output connector is used
automatically when the bandwidth extension is activated (i.e. for bandwidths
> 80 MHz).
4.2.8 Sync Trigger Input and Output
The "Sync Trigger Input / Output" connectors allow you to synchronize several
devices (for example two R&S FSWPs) with respect to the trigger signal, but also
the reference frequency. A 100 MHz signal can be output as a trigger or reference
signal to another device, and an external trigger or reference signal can be
received at the input connector by the R&S FSWP.
4.2.9 AUX Port
The 9 pole SUB-D male connector provides control signals for controlling external
devices. The voltage levels are TTL compatible (max. 5 V).
Pin Signal Description
1 +5 V / max. 250 mA Supply voltage for external circuits
2 to 7 I/O Control lines for user ports (see
User Manual)
8 GND Ground
9 READY FOR TRIGGER Signal indicating that the instru-
ment is ready to receive a trigger
signal (Low active = 0 V)
